The results of conventional strabismus surgery are always somewhat uncertain, despite the most careful preoperative assessment. Yet it is important to achieve good alignment in patients with fusion potential who have intermittent exotropia, extraocular muscle paresis or a restrictive syndrome. Planning surgery for patients with thyroid myopathy and planning reoperations is particularly difficult. In 30 patients with various strabismus disorders the use of adjustable sutures proved safe and of value; the results were unacceptable in only 5 of the 28 patients with horizontal deviations. The inconvenience for the surgeon and the extra discomfort for the patient seemed outweighed by the predictability of the surgical result.

At Flinders Medical Centre in Adelaide, eye surgery under local anaesthesia (peribulbar block) has been carried out in the day ophthalmic surgery unit since 1987. In a subset of 536 patients, 112 patients required additional anaesthesia (supplementary retrobulbar block or regional muscle infiltration) to achieve full ocular paresis, and 10 patients required intraoperative supplementation of anaesthesia because of discomfort. Six patients had their surgery postponed (one had a retrobulbar haemorrhage and five became anxious after the procedure commenced). Sedation was rarely required and there were no adverse effects of the anaesthetic on surgical procedures or patients' vision. The authors conclude that peribulbar block provides satisfactory anaesthesia and that day ophthalmic surgery is safe and effective.

Suprascapular nerve entrapment (SNE) in the suprascapular notch is a rare entity that must be considered in the differential diagnosis of radicular pain, as well as that of shoulder discomfort. Over a period of 10 years (1985-1995), the authors treated 28 cases of SNE in 27 patients by surgical decompression of the nerve. One patient underwent operation bilaterally within 5 years. Five patients presented with a history of trauma to the shoulder region. In three patients, a ganglion cyst was the origin of the nerve lesion. In 16 patients, the nerve problem was primarily related to athletic activities. Eight of these patients were professional volleyball players. In the remaining three patients, there was no relationship between the nerve lesion and trauma or athletic activities. Twenty-one patients (22 cases) complained of pain located over the suprascapular notch. Seventeen patients had paresis and atrophy of both the supraspinatus (SS) and infraspinatus (IS) muscles. In 10 patients only the IS muscle was involved. One patient exhibited a sensory deficit over the posterior portion of the shoulder. Electromyography was performed in all cases. The mean follow-up period in the 25 cases (24 patients) that could be evaluated was 20.8 months (range 3-70 months). Nineteen of 22 cases with preoperative pain could be evaluated. Sixteen of these patients were completely free of pain after surgery and three patients found their pain had improved. Motor function in the SS muscle improved in 86.7% and motor function in the IS muscle in 70.8% of cases. Atrophy of the SS muscle resolved in 80.7% and atrophy of the IS muscle in 50% of cases. Surgical treatment of SNE is indicated after failed conservative treatment and in cases of atrophy of the SS and IS muscles. The authors recommend the posterior approach, which minimizes risks and complications and produces good postoperative results.

In order to evaluate complications due to cervical spine surgery using the anterior cervical approach a prospective study was conducted on 125 patients. ENT examination with the fibroscope was employed for all the patients before the procedure. The patients were operated on under general anesthesia and were intubated with an armoured tube, and then were placed in an intensive care unit for 24 hours. Assessment of deglutition and an ENT examination were performed the day after surgery. Before surgery, two cases of vocal cord paralysis were noted. 111 patients (88.8%) presented with subjective disorders: problems such as sore throat, odynophagia, dysphagia, dysphagia with overspill and hoarseness were respectively noted in 55 (44%), 34 (27.2%), 32 (25.6%), 11 (8.8%) and 13 (10.4%) cases. Dyspnoea was found in 2 cases (1.6%). 117 patients (93.6%) presented postoperative anomalies which were found on the posterolateral pharyngeal wall, on the arytenoids and on posterior third of the vocal cords. Inflammatory and/or swollen lesions were slight, moderate, significant or very significant in respectively 22.4%, 22.4%, 15.2% and 1.6% of cases. Very significant circumferential swelling of the pharyngeal wall and of the arytenoids was responsible for two cases of respiratory distress, and the patients required reintubation and return to theatre. Severe pharyngeal lesion correlated with duration of surgery (r = 0.20; p < 0.05), with the number levels of fusion (r = 0.02; p < 0.02) and with the age of the patient (p < 0.02). Six patients presented problems of mobility of the vocal cords: 3 had a right vocal cord paresis which was temporary and 3 had paralysis, also on the right but which persisted. There were no other complications. It is concluded that (i) ENT complications are frequently found in postoperative cervical spine surgery using the anterior cervical approach, some of them being severe. An ENT examination must be performed before the procedure for legal reasons. It is also recommended in the postoperative period in the case of discomfort; (ii) patients need to be placed in an intensive care unit during for the first 24 hours (iii). This study needs to be attended over more patients (iv) comparison with a control group of patients having non cervical surgery and intubated in the same way is needed to differentiate lesions related to surgery or intubation.

Degos' disease is a rare multisystem vasculopathy of unknown etiology. We report a 44-year-old man who presented himself with gait and sensory disturbances mainly due to thoracic transverse myelopathy four years after the appearance of many characteristic umbilicated papules over the trunk and extremities. He did not complain of abdominal pain or discomfort. Laboratory, electrophysiological and imaging studies did not show any characteristic change, except for the increase of protein contents and cell counts in the cerebrospinal fluid. We tried methylprednisolone pulse-dose therapy (1,000 mg/day x 3 days) five times, but this patient's neurological condition worsened stepwise after it, although the appearance of new skin lesion was suppressed. Intravenous infusion of ozagrel sodium and cyclophosphamide (1,000 mg/day) were also ineffective, and this patient died of respiratory failure after showing oculomotor paresis and comatose state. Necropsy revealed Degos' disease-specific vasculopathy in the central nervous system and the gastrointestinal tract, where occlusions of small-sized arteries and veins due to the intimal thickening were evident. The tissue necrosis was macroscopically remarkable in the brainstem and the thoracic spinal cord. The efficacy of steroid therapy for this disease should be investigated more carefully.

Based upon an inception cohort of 30 patients with severe Frey's syndrome, after conservative parotidectomy, the technique and the results of intracutaneous injection of botulinum toxin type A are presented. The skin surface involved with Frey's syndrome was managed with intracutaneous injection of 2.5 international units of botulinum toxin type A per square centimeter. A minimum follow-up of 16 months was achieved. The only adverse side effect encountered was a temporary paresis of the upper lid noted in 2 patients. Frey's syndrome vanished within 2-5 days from the intracutaneous injection of botulinum toxin type A. Frey's syndrome was controlled in 53.2% of cases (17/30) after the initial injection of botulinum toxin type A. Five of the 13 patients with recurrence of Frey's syndrome elicited to undergo a watch and wait policy due to the lack of discomfort induced by the recurrence. The remaining eight patients with recurrence of Frey's syndrome were successfully managed with a secondary intracutaneous injection of botulinum toxin type A. Such preliminary data, together with the review of the literature suggests, that the intracutaneous injection of botulinum toxin type A should now be the first line treatment option in patients with severe Frey syndrome.

The case is presented of a 47-year-old woman with an 8-week history of persistent right ear discomfort and a 2-week history of unilateral parotid swelling, as well as peripheral paresis of the facial nerve. The case points to the difficulties encountered when Wegener's granulomatosis presents in an unusual and varied way which mimics a malignant tumour of the parotid gland. To our knowledge, the association of parotid gland involvement and facial palsy in Wegener's granulomatosis has not previously been described in the literature.

Aim of this study was to determine sensitivity and specificity of the mastoid vibration test in patients who had suffered an attack of vestibular neuritis. Results were compared with the caloric test and two bedside tests of vestibular function (head shaking test and head thrust test). Results are reported in 28 patients who had a residual vestibular deficit 6 months after acute neuritis and in 25 healthy subjects. Mastoid vibration nystagmus was evoked in 21 patients but not in controls. In these patients, mastoid vibration test had a sensitivity of 75% and specificity of 100%. Since one patient had inverted mastoid vibration nystagmus, specificity of identification on the pathological side was 95%. Sensitivity of the test increased with increasing severity of the vestibular lesion. Indeed, mastoid vibration nystagmus was induced in 93% of patients with caloric paralysis and in 58% of those with caloric paresis. Nystagmus could usually be modulated or elicited by stimulation of either mastoid. In the few patients in whom mastoid vibration nystagmus was elicited only from one side, or when there was a clear difference in intensity of the nystagmus induced on the two sides, the stimulated side was more often the affected side. Four patients still showed spontaneous nystagmus. The caloric test was abnormal in 26/28 patients (93%) with paralysis in 16 and paresis in 12; 71% of patients had a head shaking induced nystagmus: 64% had an asymmetrical response in head thrust test. In conclusion, mastoid vibration test was overall more sensitive than head thrust test. Mastoid vibration test was slightly less sensitive than head shaking test in patients with severe residual deficit and more sensitive in patients with partial deficit. Mastoid vibration test, a valid, low cost clinical screening test for rapid detection of asymmetrical vestibular function, does not cause patient discomfort. It is suggested that this test be included in the diagnostic workup of all patients with suspected vestibular dysfunction.

Pain in the paretic upper limb is a common complaint in the post-stroke patients. It usually affects shoulder joint and, less frequently, wrist and hand. Pain is usually accompanied by limited mobility of the shoulder and sometimes by swelling of the hand and wrist. The aetiology of these complaints remains unclear. The objective of the study was to evaluate the incidence of pain, limited mobility, swelling and other signs that appear in the paretic limb within the first year after stroke. Forty-five stroke patients treated in the Department of Neurology in 2000 who answered the questionnaire concerning type, localization and intensity of the complaints from paretic upper limb were included. Twenty-six patients (58%) had a painful shoulder, wrist or hand. These complaints concerned women more frequently than men (71% vs. 46%, consecutively), younger patients aged below 55, and those who initially had more severe paresis. Symptoms and signs appeared within first month after stroke in majority of patients, and 70% of patients considered these symptoms very disturbing, significantly deteriorating the dexterity of the paretic limb. Thirty five percent of patients complained of limited mobility in the shoulder joint, 18% had incomplete mobility of fingers in the paretic limb. Twenty two percent of patients had swollen wrist and hand, and 24% had a discoloration and trophic changes of the skin in the paretic hand. Cold intolerance by means of freezing sensation in the affected limb was experienced by 58% of patients. Three patients had complaints both in shoulder and hand, with accompanied swelling, trophic changes and vasomotor disturbances in the hand, what fulfilled criteria for the diagnosis of shoulder-hand syndrome. The results of the study show that upper limb pain and limited mobility are common complications of the stroke. Usually underestimated by family doctors these symptoms and signs cause a significant discomfort for the patients and delay the recovery of the paretic limb.

Regional anesthesia has an expanding role in upper extremity surgery. Brachial plexus blocks offer several advantages including providing effective analgesia, reducing narcotic requirements, and facilitating ambulatory care surgery. Despite the popularity of nerve blocks, the surgeon must not forget the complications associated with regional anesthesia. This article describes a case of symptomatic phrenic nerve palsy after supraclavicular brachial plexus block in an obese man. A 46-year-old obese man underwent a left-sided supraclavicular block in preparation for decompression of Guyon's canal for ulnar mononeuropathy at the wrist. The patient experienced acute-onset dyspnea, chest discomfort, and anxiety, and physical examination demonstrated reduced breath sounds in the left hemithorax. Chest radiographs documented elevation of the left hemidiaphragm consistent with an iatrogenic phrenic nerve palsy. The patient was admitted for 23-hour observation and underwent an uncomplicated ulnar nerve decompression under Bier block anesthesia 1 week later. No long-term sequelae have been identified; however, there was a delay in surgical care, admission to the hospital, and transient pulmonary symptoms. We attribute this complication to significant abdominal obesity causing compromised pulmonary reserve and poor tolerance of transient hemidiaphragmatic paresis. In recent studies, waist circumference and abdominal height were inversely related to pulmonary function. We suspect that the incidence of symptomatic phrenic nerve palsy associated with brachial plexus blocks will increase as the prevalence of obesity increases in this country.
